I-DRIVE TECHNICAL MANUAL – OPERATION PG DRIVES TECHNOLOGY
8 Status Indication
Depending on the machine model, the status indicator may be a single lamp (or LED) or a TruCharge battery gauge and
diagnostics display. Both types indicate the status of the controller.
A number of supposedly faulty controllers returned to PGDT are subsequently found to operate correctly. This indicates that many
faults are due to problems on the machine rather than within the controller.
8.1 Single Lamp and LED Status Indicators
8.1.1 Status Indicator Steady
This indicates that all is well.
8.1.2 Status Indicator Flashes Slowly and Continuously
The controller is functioning correctly, but the battery voltage has fallen below the level set by either
Battery Lockout Voltage or
Battery Lockout Voltage 2.
Do not operate the machine if the battery is nearly discharged.
8.1.3 Status Indicator Flashes Slowly, Pauses, Then Flashes Slowly Again (even with throttle released)
The controller safety circuits have operated and the controller has been prevented from moving the machine.
This indicates that there is a trip. Please follow this procedure:
• Switch off the machine.
• Make sure that all connectors on the machine are mated securely.
• Check the condition of the battery.
• If the fault persists, count the number of flashes after a pause and then try using the self-help guide in
Section 8.3.
• Switch the machine on again and try to drive. If the safety circuits operate again, switch off and do not try to
use the machine.
• Contact your service agent.
When a system trip occurs and the parameter Diagnostic Flash Sequence has been set to ‘PG’, a series of flashes will be
reproduced on the lamp or LED status indicator. The number of flashes will mimic the TruCharge Status Indicator Trip Types, e.g.
when the lamp or LED flashes 2 times, pauses, then flashes 2 times again etc., the controller has detected a bad motor
connection. Refer to
Section 8.3 for the full list of trip types.
8.1.4 Status Indicator Blinks On Every 3½ Seconds
The controller has entered Sleep Mode. Recycle the power to reset.
8.1.5 Status Indicator Flashes Rapidly And Continuously (even with throttle released)
The controller safety circuits have operated and the controller has been prevented from moving the machine.
This indicates that there is a trip. Please follow this procedure:
• Switch off the machine.
• Make sure that all connectors on the machine are mated securely.
